| titleOfInvention | Surge protection circuit for lightning protection of acquisition system |
| abstract | The utility model relates to the field of protection circuits, in particular to a surge protection circuit for lightning protection of an acquisition system, which is provided with a transient suppression diode and is characterized by also comprising: the ceramic gas discharge tube is connected between the TXD interface and the RXD interface of the protection circuit in parallel, and the self-recovery fuse is connected with the ceramic gas discharge tube to eliminate parasitic coupling generated by current change. The utility model has the advantages that the ceramic gas discharge tube is utilized to absorb the first-stage heavy current, most surge current is absorbed, after the decoupling treatment of the self-recovery fuse, residual voltage flows to the transient suppression diode to obtain lower clamping voltage, and the RS232 chip is protected from the influence of surge impact. |
